Iran Threatens to Close Strait of Hormuz as Naval Blockade Tensions Escalate

Tehran, April 18 (IANS) – Iran’s Parliament Speaker Mohammed Bagher Ghalibaf has issued a stark warning to the United States, threatening to shut down the strategically vital Strait of Hormuz if the U.S. continues its naval blockade of Iranian shipping. The warning comes amid escalating tensions between the two nations after the U.S. President indicated that maritime restrictions would remain in “full force.”

In a statement posted on social media platform X, Ghalibaf directly challenged U.S. policy, asserting that Iran possesses both the capability and willingness to close the strait, which serves as a critical global energy chokepoint through which approximately 20% of the world’s oil supply flows daily.

“The maritime route works for everyone or for no one,” Ghalibaf declared, signaling Iran’s readiness to take drastic measures if pushed further by American naval restrictions.

The Strait of Hormuz, a narrow waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea, is only 21 miles wide at its narrowest point. Any disruption to shipping in this area would have immediate and significant impacts on global energy markets, potentially sending oil prices soaring and disrupting supply chains worldwide.

Energy analysts have long considered the strait a potential flashpoint in Middle East tensions. “If Iran were to follow through on this threat, we could see oil prices jump by $15-20 per barrel overnight,” said Marcus Reynolds, an energy security specialist at the International Energy Forum. “The global economy, still recovering from recent supply chain disruptions, simply cannot afford such a shock.”

The naval blockade that triggered Iran’s response represents the latest chapter in the long-standing conflict between Washington and Tehran. U.S. officials maintain that the restrictions are necessary to enforce sanctions designed to limit Iran’s nuclear program and curtail what they describe as Tehran’s destabilizing activities across the Middle East.

The Iranian government, however, views the blockade as an act of economic warfare. Foreign policy experts note that Iran’s threat to close the strait is not unprecedented – similar warnings have emerged during previous periods of heightened tensions, though they have never been fully executed.

“This is a calculated escalation in rhetoric,” explained Dr. Sarah Kamal, a Middle East analyst at Georgetown University. “Iran knows that closing the strait would invite severe military consequences, but they’re signaling their unwillingness to suffer economic strangulation without response.”

The confrontation occurs against a backdrop of stalled nuclear negotiations. After the U.S. withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in 2018, Iran has gradually increased its uranium enrichment activities, moving closer to weapons-grade material while insisting its program remains peaceful.

Regional allies of the United States, particularly Saudi Arabia and the United Arab Emirates, are monitoring the situation with growing concern. Both nations rely heavily on the strait for their oil exports and have urged diplomatic solutions to prevent further escalation.

“This is precisely the kind of situation that could spiral out of control through miscalculation,” warned former U.S. diplomat Richard Haass in a recent interview. “When countries make threats involving critical infrastructure, the risk of unintended consequences rises dramatically.”

International shipping companies are already adjusting their risk assessments for the region. Insurance premiums for vessels transiting the Persian Gulf have reportedly increased by 15% since the latest exchange, according to industry sources.

The European Union has called for restraint from both sides, with the EU’s High Representative for Foreign Affairs emphasizing that “dialogue remains the only sustainable path forward” in resolving the standoff.

As tensions continue to mount, global markets remain on edge, with traders closely watching for any signs of military movements or diplomatic breakthroughs that could either escalate or defuse what has become one of the most volatile flashpoints in international relations.
